How come the pictures have such bad quality ? Is it a bandwidth issue ? Or there are really constraints that are not so obvious ?
Because fundamentally it is a large object illuminated by sunlight.
- Sharlin 7mo agoIt's the night-side Earth, taken at a high ISO value to keep shutter speed fast to prevent blur.
- rvnx 7mo agoOk thank you, makes more sense, I thought it was the day-side
- Sharlin 7mo agoYes, I was also confused when I first saw it – how could the aurora be visible?! The bright sliver of atmosphere in the lower right is, of course, backlit by the sun which is itself eclipsed by Earth. It's the near-full moon that provides most of the illumination here. Besides both auroral rings you can also see airglow, city lights, and lightning flashes, it's a marvellous photo.
